    Product Description

    The optical system for reducing the divergence of the laser beam at large distances.
     

    An antireflective coating is applied to both surfaces of lens providing extraordinary light transmittance of >99,7 % for the whole 400nm - 700nm spectrum.

    The lenses have been designed in terms of shape to ensure the best cooperation with the diodes listed below.

    They can be also used with other laser diodes. If you have any questions regarding the proper selection of lenses to be used with your laser diode, please feel free to contact us.

     

    The lens system is designed for 520 nm laser diodes:

    1000 mW Nichia (NDG7475)


    A test of the optical system with Nichia 520 nm 1000 mW (NDG7475) laser diode is shown below. Using this pair of lenses it is possible to reduce the width of the laser beam about 2,5 times.
